Level 2 6L80E / 6L90E

Level 2 6L80E / 6L90E Transmission. This Super Duty 6L80E transmission comes with our Full Billet torque converter, that has a very large Red clutch. Full Billet means both the converter housing and the clutch apply piston are both billet. This converter is built in-house at PATC. The Alto Red Eagle Power Packs are here and we install them in our Super Duty 6L80E transmissions. The 3-5-R direct clutch has 14 single sided clutches and the 4-5-6 overdrive clutch has 18 single sided clutches. These are two weak points in the 6L80E transmission. This is a 75% larger clutch apply area in the 3-5 clutch and a 50% larger clutch apply area in the 4-5-6 clutch. We use our exclusive PATC / Alto Kryptonite clutch lining on the other clutch sets. As an added bonus this transmission has an oversize filter. You can buy this Super Duty 6L80E transmission and Full Billet torque converter for the price shown here plus a core charge on the transmission and converter. Custom tuning must be performed to the TCM to accommodate the new parts.
